Bogen s UTI1 is a single-zone telephone interface that is compatible with all standard analog port types. A background music (BGM) input with variable muting coordinates music and page announcements. An additional audio output provides a page only function (no BGM) for application flexibility. A built-in 24V DC, 1A power supply is provided for powering amplified speakers. Paging volume controls are provided for each of the outputs. Contact-triggered tones and night ring signals, as well as programmable AUX relay contacts, are all programmed using DTMF tones through the dual-purpose override input. *NOTE* The TAMB2/PS is now EOS. The UTI1 is a great substitute for 95% of use cases. See the documentation section below for a full feature comparison guide.
